INTERLOCKING SHEETSTEEL FRAME FOB LNCfiORAGE PLASTER BOARDS.

' Application filed December 26, 1923." Ser1al No. 682,852.

To all whom it may concern.

Be it known that I, IsAnonn POMERANTZ, a citizen of the United States, residing at St. Louis, State of Missouri, have invented a 5 certain new and useful Improvement in an Interlocking Sheet-Steel Frame for Anchorage of Plaster Boards; and I do declare'the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'usethe same, reference being had to the-accompanying drawings, and to the letters and figures of refer ence marked thereon, which forn'ta part of this specification.

This invent on relates to crectin of partitions formed of an interlocking s eat-steel frame to which plaster boards are fastened and ready to .be covered, both sides, with gypsum plaster. I obtain in this manner a system of fire and sound resistive nonbearin partitions fulfilling the requirement of big -class fireproof construction at low ultimate cost. 4

My system of partitionconstruction possesses great rigidity even unplastered. When plastered, its strength and rigidity exceeds 1 any type of open lath and channel stud par-.-

tition. Its stren this not entirely dependent on plaster as in t e cases of many othertypesQ The principal object of the invent1on 15,-

to provide a system by which the plaster boards are instantly and rigidly fastened or anchored to the studs, plates and saddles,

B5 and no special tools are required to accomplish same.

Another ob'ect is to rovide means by which the stu s are readi y adjusted in distances as desired and easily fastened and.

kept in place. Y

Another object is to provide partitions of plaster boards usually made in sheets and of standard sizes, and when these are anchored up to the studs, plates and saddles according to my system, will not warp,

buckle or bulge.

A feature of my system is the reinforced design of the studs and the method of anchoring by easily and rigidly inserting the locks, or anchors into the holes provided in the projecting shouldered tongues of said studs themselves. Another feature is that said tongues are provided also with separate openings or perforations which cooperate and instantl fasten the with the plaster for holding the plaster boards.

Another and very important feature is that the shouldered continuous tongues provlded in said studs will keep .the laster board rigidly in place before the loc s are inserted for anchoring purposes.

Another feature which is also important is the fact that the sheet-steel channel forming the studs become reinforced in having the outwardly projected shouldered tongues, as er my system.

nother-feature is that a frame made in '70 the interlocking of same with the joining the floor or ceiling are rigidly held 1n lace by means of my interlocking plates. till another main feature is that not only the vertical ends of the plaster boards but also the horizontal ends are rigidly anchored, thus preventing warping, buckling or bulging of same.

My systemconsists of: 1--Anchoring reinforced channel stud-s provided"; with outwardly projected and shouldered tongues with'means to rigidly plaster boards to the said stu s. Y

2-Special floor and ceiling channel plates with means to adjust and hold in place the 5 reinforced studs.

.3-Anchoring saddles with. the featuredpurposes to rigidly keep in place the horizontal ends of the plaster boards anchored on both sides of the studs.

4-The locks or anchors which fasten the; I

plaster boards to thestuds and to the sad-" dles, said locks engaging into holes provided for this purpose.

In accomplishing this object, I have pro- Fig. 3 is a sectional perspective of a hollow partition made according to my invention, comprising the reinforced channel studs, same being held in place at the bottom to the special plate fastened to a floor. N etc the anchoring saddles.

Fig. 4 is a vertical section through a stud, showing how same is held in placeby a stop inserted into the groove of a bottom plate.

Fig. 5 is a perspective showing the stop as formerly mentioned.

F ig.'6 is a perspective showing the lock which rigidly holds in place the plaster board to the 'studding or to the saddles.

Fig. 7' is a vertical section through part of a partition and through the saddle.

Fig. 8 is a sectional perspective of a hollow partition, according to my invention, comprising the/reinforced sheet-metal studding, showingf how the plaster boards are anchored totlfe: studs. 7 I

Fig. 9 is'apers ective of a saddle. Such a device is the rst ever used for rigidly holding in place the horizontal ends of plaster boards.

Fig. 10 isa vertical section through a stud,'showing how same is connected to a channelplatefastened to a ceiling. I am using a similar plate to that shown in Figure 4 but reversed.

F i 11 is a perspective of the special adjusta le plate to be used at top and bottom of the studs and shown in Figures 4 and 10.

Fig. 12 is a horizontal section through a stud slightly different from the stud shown in Figure 1. Such a stud is to be used in case it is desirable to fasten two layers to the stud. First a deadening pad is used and second a laster board on top of, the deadening pad: I Excepting the sectional perspective shown in Figure 3, all other designs are shown in full size. But I do not limit the sizes of the studs.

' Referring now to the drawin s by numerals of reference and particular y to Figures 1 to 11, in clusively:

1 designates the studs in channeled form consisting of a flange 9 and end flanges 7. The flanges 7 contain outwardly projecting tongues provided with shoulders 12; inclined flanges 24 and anchoring ends 5. Numeral 6 designates the perforations cut into the inclined flanges 24 acting as plaster keys. Numeral 11 designates theholes cut into the anchoring ends 5 into which engage the locks 4 to hold the plaster boards 2 to the studs 1. Numeral 14 designates the saddle consisting ofa top flange 41, having at both ends T form anchoring devices 15, provided with erforation 16 in which engage locks 17 to old in place the plaster boards 2.

Number 26 designates the special channel plate for top and bottom of studs 1. This i channel plate consists of a ,flange 27- provided with a groove 28. At the ends of the main flange 27 there are angles formed of flanges 29 and 30 in angle form. Said angles are provided with hooks 31 for the purpose of rigidly holding in place the plaster boards on the top and bottom of the partition.

Numeral 33 designates the stops placed on both sides of the studs 1, where the studs come in .contaet with the flange 27 of the channel plate 26. These stops 33 engage into the groove 28 formed into the flange 27 of said plate 26. Numeral 3 designates the plastering coat. Numeral 59 designates the slightly different stud in channeled form consisting of a flange 51 and end flanges 52. The flanges 52 contain outwardly projecting tongues provided with shoulders 53, having grooves 54. Inclined. flanges 55 are provided with perforations 56 for cooperation with the plaster and numeral 57 designates the anchoring end provided with holes 58, in which engage the locks 59 to hold in place the deadening pad 60; also the plaster board 61 on top of the pad 60, against the stud 50. Numeral 63 designates the pin engaged in the groove 54 to hold in place the deadening pad 60. Numeral 64 designates the plastering. I do not limit myself to the shape of studs, plates, saddles and locks shown upon this drawing, but any other studs, saddles ,and locks, etc., could be used'if same are provided with features claimed as part of my invention.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is:

1. A reinforcing structure for wall structures comprising studs, adjustable plates at the top and the bottom of said studs, said plates having a channeled shape and containing a groove for engaging stops to hold said studs in place and havin anchoring means for the horizontal ends 0 the plaster board.

and the portions not contacting therewith provided with perforations for the entry of plaster and for locking members.
